Moving To West Jordan, UT. Concerned about the South Valley Regional Airport Noise.

My wife and I are first time home buyers looking in the West Jordan area. We are currently interested in a house just a few blocks west of the South Valley Regional Airport. We went to tour the house on a Wednesday and noticed 4-5 helicopters fly over within a 45 minute window.

My question is how often do these helicopters fly in and out, are there times of the year when they are more or less active and does it bother the residents in the area?
